Wondering if anyone has found a step up transformer that will plug into the Ooma box (rather than one that you plug the 120V power adapter that comes with the system into)? Does Ooma provide a dual voltage power adapter for international use?

I use the following 220v converter abroad and it works flawlessly. I also run a USA based Panasonic DECT phone through that.Seven Star 100 Watt Step Up and Step Down Transformer TC-100http://www.batteryjunction.com/seven-star-tc100.htmlMake sure your converter is for continuous use.
